1. The level of risk in investing in these currencies cannot be ignored because they are not popular enough compared to other cryptocurrencies in the market. Frankly, I would not advise anyone to buy it if they are not a fan of gambling companies. The reliance of these cryptocurrencies on the gambling niche for expansion makes them limited in their capabilities in a way that makes it difficult for them to enter into competition with the rest of the major currencies, even for a short period of time.

2. Although I have never been a big fan of casino coins in general, I can say that Rollbit Coin (RLB) is one of the leading cryptocurrencies in this rapidly expanding market and has already gained huge attention in the crypto market since its launch. https://coinmarketcap.com/currencies/rollbit-coin/

3. They should have a bull run if there is no problem with the casino itself. Literally, there will be nothing preventing any of these cryptocurrencies from joining the bullrun as long as they are available for trading. Almost all currencies were included in this in conjunction with the recent rise in prices, and only a few projects were excluded in which the community lost confidence for certainly objective reasons.
